When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 6a - 8a = -2a + 9y - 6 for a in terms of y.
| 2\(\frac{1}{2}\)y - 4 | |
| -\(\frac{3}{7}\)y - \(\frac{1}{2}\) | |
| 2\(\frac{1}{8}\)y - \(\frac{3}{4}\) | |
| \(\frac{6}{13}\)y - \(\frac{1}{13}\) |
